SOLUBLE BRUSH.

Specification of Letters Patent.

Application led October 17,1911. Serial No. 655,128.

To all whom it may concern:

Be it known that I, FRANCIS W. SADL-ER, a citizen of the United States,residing at Norristown, in the county of Montgomery and State ofPennsylvania, have invented new and useful Improvements in SolubleBrushes, of which the following is a specilication.

An object of the invention is to provide a brush capable of becomingsoluble when subjected to the dissolving action of a Huid.

My invention relates more particularly to a brush body, provided withprojecting elements, soluble in water or theilike, so that when thebrush is once used in connection with a fluid, the same cannot bereusedthus insuring perfect sanitation, .l particularly when my deviceis used as a tooth brush or the like.

Reference is to be had to the accompanying drawings constituting a partof this specification, in which similar characters of reference denotecorresponding parts in all the views, and in which- Figure 1 is aperspective view of the brush. Fig. 2 is a vertical sectional view takensubstantially on the line 2-2 in Fig. 1. Fig. 3 is a perspective view ofmy brush showing the same in connection with a holder. I

Referring more particularly to the views, I provide a brush body 10,preferably rectan lar in shape and having the sides thereof slightly"inclined, the said brush body being adapted for slidable engagementwith a holder 11, provided with a handle 12. Integrally formed on thebrush body `10 and projecting upwardly Vtherefrom are a series ofprojections 13, such as bristles or teeth, the said projections beingpreferably conical in shape and composed of a substance which becomessoluble when subjected to the action of a fluid. The

brush body 10 and projections 13 are pref` erably made of a mixture ofantiseptic formaldehyde tooth powder and paper pulp and an adhesive ofan antiseptic or sanitary nature is mixed with the mentioned ingredientsto act as a binder therefor.

In the use of my device, the brush body 10 is preferably mounted on aholder, such as the holder 11, shown in Fig. 3. Assuming that theparticular brush disclosed is used as a tooth brush, when theprojections thereof come in contact with the saliva in the mouth, theaction of the saliva onthe projections will cause the same to becomesoluble so that after one application, the projections will be destroyedso that the brush cannot be reused, it being necessary to provide a newbrush when it is desired to clean the teeth a second time.

From the foregoing description, it will be seen that a device isprovided, which is absolutely sanitary in its application and use and inwhich the projections of the brush, being soluble are destroyed andrendered unfit for use after the first application thereof.

It will be understood that the projections mentioned herein can befashioned similarly to bristles or teeth and that the scope of theinvention is defined in the appended claims.

I claim l. A tooth brush having an acting surface composed of pointedprotuberances of a material soluble and disintegrable under theinfiuence of moisture and the rubbing action of said protu-berancesagainst the teth, the said protuberances being impregnated with anantiseptic cleansing agent.

2. A tooth brush having an acting surface composed of pointedprotuberances of a material soluble and disintegrableunder the influenceof moisture and a rubbing action of said protuberances against theteeth, the said protuberances being molded from a material of thecharacter described impregnated with an antiseptic, a cleansing agent,and an adhesive.

Patented Oct. 6, 1914.1

3. A tooth brush having an acting sur face composed of pointedprotuberances molded from paper pulp, an antiseptic, a cleansing powder,and an adhesive, said protuberances being soluble and disintegrableunder the iniiuence of moisture and the rubbing action of saidprotuberances against the teeth, whereby in the cleansing actiondisintegrated particles of the protuberances carrying the antiseptic aent will be left in the interstices between t e teeth.

In testimony whereof I affix my signature in presence of two witnesses.
